Tenant statistics example (based on v2 API/DSL)

The example shows how Mistral can be used to gather information about OpenStack tenant. The workbook tenant_statistics contains two workflows that solve the same task: they send an email report containing a number of virtual machines, number of active virtual machines and number of networks. Workflow tenant_statistics_plain runs runs all its tasks sequentially one after another. Workflow tenant_statistics_join runs two tasks in parallel to gather tenant metrics, waits their completion using join workflow control and after that sends a report.

To run the example:

1. Load workbook from tenant_statistics.yaml:

   mistral workbook-create tenant_statistics.yaml

2. Create input.json file containing workflow input parameters as follows:

   {
       "to_email": "admin@my_domain.com",
       "from_email": "my_address@my_domain.com",
       "smtp_server": "smtp.my_domain.com:587",
       "smtp_password": "my_password"
   }

3. Start workflow:

   mistral execution-create tenant_statistics.tenant_statistics_join input.json

4. Using execution id from the previous step wait for completion (workflow SUCCESS state):

   mistral execution-get <execution_id>

5. Check email inbox for the expected report.
